There are many more variations on the wedge but we need to address the one by Kajiwara:

Kajiwara continued  

This is main line as presented on the parent page, invented or articulated by Kajiwara Takeo. KataGo doesn't like it for White, giving away a big corner for influence but not strength.

Hane

Main line  

Unless the top right is yet undisputed, in which case Black may be more adventurous, Black will play lightly here with and take up a position at the top left.

= Wedge into the elephant's eye

Main line ctd  

Both capture 2 stones but again Black has a blighted pincer stone.

Variation  

White grabs the corner but there's quite a lot of aji.

= Katago's preferences

Kick

Main Line  

emphasizes the corner. This variation can be attractive to White if there is influence on the left side to cooperate with.

Extend

Main Line  

If Blacj has influence at the top to cooperate with, he might extend up against the press. If , Black can reinforce the corner and then the stones go walking

Keima

Main Line  

A first choice is to jump here and both can treat the situation lightly, with a becoming urgent soon.
